What Is an Atom in Chemistry? In the world of chemistry, an atom is matter, which makes up everything that is tangible (items you can touch) in the world. One important property of an atom is that it can't be broken down any further with any type of chemical means because it is i...

What is an atom? The structure of these microscopic building blocks drives the chemistry of the universe (Image source: Getty Images) Atoms are the building blocks of everything around you, from the cells in your body to the cup of tea in your hand. Made from elementary particles and held...
Dalton's atomic theory formed the groundwork of chemistry at that time. Dalton envisioned atoms as tiny spheres with hooks on them. With these hooks, one atom could combine with another in definite proportions. But some elements could combine to make different compounds (e.g., hydrogen + oxyg...
Each element is comprised of atoms that are unique to that element; hydrogen atoms are different from gold atoms, which are different from neon atoms. Lesson Quiz Course 12K views History The word 'atom' derives from a Greek word that means 'indivisible,' and it was first used to ...
What is anion and cation in chemistry? Losing and Gaining Electrons: Atoms are the smallest building blocks of matter, and they have within them subatomic particles called protons, neutrons and electrons. Electrons orbit the nucleus of the atom in various energy levels, and are involved in bondin...
Look up the atomic masses of carbon and oxygen. This is the number of grams per mole of atoms. Carbon (C) has 12.01 grams per mole. Oxygen (O) has 16.00 grams per mole. One molecule ofcarbon dioxidecontains 1 carbon atom and 2 oxygen atoms, so: ...
Would you consider a single unit of hydrogen to be an example of an atom? Keep in mind, most hydrogen "atoms" do not have a proton, neutron, and electron. Giventhat the number of protonsdetermines the identity of an element, many scientists consider a single proton to be anatom of the...
